[Q] Cannot factory reset the phone - Xperia Z3 Q&A, Help & Troubleshooting

Hello guys,
Got my Z3 phone today, but there are several bugs in the operating system. I cannot even unlock the phone once it is locked. Twitter and facebook does not work at all. All I get is a blank screen.
So I tried to factory reset, but nothing happens when I click on "Erase everything" button. Anybody else experiencing these issues?
Thanks for any help.

No. How are you doing anything if you can't unlock it?

It worked only sometimes. But I found the issue anyway. It was the SD card in my phone. Once I remove it everything works. But not sure why a SD card will cause so many issues!

Urgent!!! Help needed!!! No service problem!!!

I am new to xda. I haven't ran into a problem yet that i couldnt find a solution to....UNTIL NOW!!!
I have an incredible 2. It is rooted, and DID have a cm7 OS. Today, differentPps on my pho.e kept opening and then being foreclosed. Naturally, I rebooted my phone to see if that would fix the foreclosing problem. However, THE REBOOT MADE PROBLEMS WORSE. Now, my phone shows "no service." It shows "unknown baseband," "unknown phone number" and won't receive/send texts/calls. I can only use WiFi to use the internet. I tried factory reset, (through cm7 and the phone itself) I also tried downloading a new radio and cm9. Help NEEDED ASAP!!!! WHAT ELSE CAN I DO?!!

If you're referring to restoring back to stock Rom, I already have.

Yes, I've tried a couple times.
Try
Try hard resetting, which means clearing all data, and wiping cache (if it is that bad)
or
Try doing some of the previous steps again....
Hope It helps
I have same type of problem but after trying these instructions, I found the solution of the problem. Simply try them step by step and you will get results.

Tried hard resetting, wiping dalvik cache and cache partition. Still nothing.
However, slight change- after setting it back to stock, switched it over to cm7.2. Now, I have the roaming indicator flashing, but still cannot make calls or send texts. Before, while trying a new Tom, it would bring me to the same point, ^ but when I would select regular reboot, it would put me back with "no service."
It may happens.
Restart your phone and try then.

What instructions are you referring to? And I've tried, the most simple and generally harmless to extreme wiping and resetting everything I had. Let's say I'm just fit to be tied. This is a nightmare!!!

It happened to my sim card..no idea why..I was flashing different rooms and modems but finally swapped sim just to test ( I didn't really think that sim would be the culprit) but it worked on different..no idea as to why sim stopped working.

the spotify app.. nothing else
I can't understand how it can disappear without any update. Like Samsung sat a date in the system it should disappear on
Maybe it's there when we wake up tomorrow.
i am now having this problem, the phone rebooted itself which has been reported on the net by lots of people and after i downloaded an app i noticed that this mobile data icon has disappeared. i have about 32 gb of space left on my phone so i dont understand what has happened here.
happened to me to today , 920i not rooted, Saudi Arabia
So what was the point of OTA update? What's changed beside disappearing toggles?
I'm having the same issue here in Ireland since yesterday. Spoke with Samsung support and they said factory reset should fix it but I haven't done it yet
Has anyone tried a factory reset to see if it worked?

I've read that some people tested it and factory reset is not working as far as i know... If you have rooted your phone, there are some solutions exist. Otherwise, we have to wait for a fix.

Download Galaxy Tools and third from the bottom is an option that enables them all. Root required.

great tip, but due to the hardware problems I've had I rather not root (and yes I know that pingpongroot doesn't trigger kn0x).

[Q] (Samsung Young 2) Can't encrypt device after format

Hi guys, I'm having a problem and a friend directed me to this website, hope I'm not breaking the rules or anything by posting here.
I formatted my phone today cos I felt it got too laggy lately, everything went alright, phone is working, it got decrypted, I synced samsung/google and backed up all of my data and apps., so far so good. Then I went to actually put a security pattern but I got surprised it only let me chose "password" the rest of the choices are grayed... I read online some people said I need to go to Security>Clear Credentials, but that also can't work since it's also gray. I tried to uncheck the Device administrators (Android Device Manager) but that didn't help either. I rebooted, and still no solution. I could probably try "Install from device storage" but then I don't know what to chose? I really have no idea how android works, it would be a great if anyone can help!
Update: I also went on Developper Mode but still nothing changed.
Update: I tried putting a password on and now I have to use a password everytime I unlock it fml... can't turn it off

Basically this problem is solved by clearing credentials and disabling device administrators...But as u said its not works for you...
So, first do a factory reset... Then check.. If not works check if clear credentials option is highlighted... If yes..clear it...and see it cleared..Or not...or what it says if failed....
Disable every device administrators...
And report what happens
I did a factory reset and backed everything still the same problem.. I think I'll try again without restoring anything hmm could the SD card be the problem here? should I format it as well?

What have you restore after format.. I mean which type data?
Edit: there's must not issue with sd card.. And if u think there is.. Just remove sdcard not format it..
Apps, wifi passwords, wallpaper, but even when I didn't restore it's the same problem, oh yea I already formatted it without an SD (first time) and that was when I discovered the problem

If u still face problems.. U can flash the stock rom via odin
That sounds complicated and I don't have any usb cable I think I'll just stick to CM Locker app

S6 reboots when locked

I have a HUGE problem. Everytime i lock my phone or it locks itself, it turns off or reboots.

As far as I can tell it is not. It happens on fresh installs as well as backups :/
I think I finally got rid of the problem by restoring from an old backup through Switch.
Been 30 mins and no reboot yet.
Will come back after work with results from the day.
Update: back to rebooting.
Doesn't happen when an app is playing music/radio (Spotify etc)
Is there any way to get back to 100% stock?
Had to use twr to get out of bootlooping.
Or a link to get a working custom rom.
SMG920K is my model. Swedish version.

Optimization apps problem (CM13 incremental)

Hi,
I did all the steps, however, I have a problem. I tried to do the same things again and again and I checked if I had been using the correct version; all were ok but the phone enters loop mode when it is optimizing apps. The phone is restarted without stopping in the same point, I can't access to desktop.
Anyone can help me?. Thanks!
P.S: I tried to use my poor level of English. Sorry

Same here, my phone worked perfectly on the new CyanOS 13, then I tried to disactivate Google Now and I started to have the same infinity bootloop, in TWRP I tried wipe caches but after apps optimization i have your same bootloop...
I think mine and your problem is a Google apps problem

Hi!. I solved my problems, I can help you guy. For me, the key was to download these drivers: motorola-global-portal.custhelp. com/app/answers/detail/a_id/88481 (Sorry, I need more than 10 messages to send a link, please, erase the spaces...) (from Motorola). I sent a fastboot image and all the problems were solved.
